Step-by-step explanation:
we solve for x
15x-(2/x)>1. /*x
15x^2 -2 > x. /-x
15x^2 -x -2 > 0
Solve the quadratic at zero
15x^2 -x -2=0
using the quadratic formula
x1,2 = [1+-sprt((-1)^2-4(15)(-2))]/2(15)
= [1+- sqrt (121)]/30
= [1+-11]/30
x1= 12/30= 2/5
x2= -10/30= -1/3
therefore this positive parabola is greater than zero or positive when
x< -1/3 and x> 2/5
Answer:
Step-by-step explanation:
In the two similar triangles, Angle 1 and Angle 4 are alternate interior angles.
Vertical angles prove that Angle 3 is congruent to angle 6.
The triangles are similar because alternate interior angles are congruent.
Answer:
Same
Step-by-step explanation:
The answer is (C) because from 1976 - 1978 there was a bit deflation
We set up an equation: 3*? -2= 13
⇒ 3*?= 13+2 (inverse operation)
⇒ 3*?= 15
⇒ ?= 15/3 (inverse operation)
⇒ ?= 5
The correct answer is c. 5.
